Cheers for the info guys!
As for the second year, in my opinion stay well clear of the 4 stats modules. Maths stats A is just an absolute nightmare with a jan exam which is really tough! The average this year was below 40%, and then it got moderated, (for me 8% higher). I've also heard that maths stats B and random events are ridiculously hard as well. As for the easiest module stochastic processes it turns out not to be so easy as it is rumoured to get scaled down every year! I expected to get well over a first with it but only got 65%!
Yes algebra 2 is extremely .......................... extremely hard but you'll have to fail just like everybody else does! Metric spaces is really hard as well, but its pretty damn core if you want to do the 4 year degree it would seem! The exam is about half definitions as well though.
PDE's is really good, very lenient marking this year, i would recommend it if you can put up with lecturer who is really nice but always goes out of his way to ask you whether everything is ok!
The second year essay takes up lots of time for not that much gain in the end as it is only 6 cats, so moderate your time well. Sometimes its better to work on assignments when everyone else around you is working on the essay.
Vector analysis is a good module looking back on it because it had a really easy exam. Everyone disliked the lecturer though who may be changing so it shouldn't matter.
If you haven't taken number theory i would advice taking it in the second year.
MNN is a good module, don't have a clue what happened in the lectures though! Except the one time someone got dave wood a shopping trolley full of beer! The last assignment is also hard, so try to do as well as you can on the first one.
Intro to biology was a complete farce, i didn't like the lecturer, he asks for too much crowd participation. And the exam had loads of errors in, so it got marked up drastically. Didn't really learn much though, the whole module can be done on first year diff. eqns knowledge! So I probably recommend it.
Everything else is ok i suppose,... depends how good you are!
